I've been using Castrol RX Super 15w40 up till now. The next oil change with be SAE 30. I'm going to save the 15W40 for my winter oil change.

The low-sulphur diesel you get these days doesn't lubricate the injection pump adequately, shoterning its life. The additive provides the necessary lubrication, aids in separating water, prevents fuel gelling in winter, and boosts cetane value of fuel (for more power).

I was using the Stanadyne fuel additive since I got the truck (8 months ago). I ran out and couldn't find the Standyne again, so I'm using Gunk diesel additive now.

Just started running Delvac1, the local Traveller's America had it miss-priced as Delvac 1300! Something like 9 or 10 bucks a gallon, normally it's around 5 bucks a qrt.!

I bought all they had, 10 gallons of it! I only put about 10-15K a year on the Blazer and I shouldn't have no problems with this oil lasting all year. At the worst it should be good for 6 months. Really, it is one of the best oils out there. Good stuff.

I'll be running it for quite a while! /forums/images/graemlins/thumb.gif

Oil weight aside, make sure the oil you use is rated for diesel use - identified by CF/CG/CH service category instead of SG/SH/SJ. Its made to deal with extra soot/fuel that ends up in the oil of a diesel engine.

When I first got my diesel, I was going to use the 20W50 I had sitting around until I read the bottle and did some searches on the Web.

Ive been running CaseInternational 30 weight, the same stuff we use in our tractors at the farm. We buy it by the 5 gallon bucket. I ran it in my C10 Scottsdale till i killed the 700R4 towing, and now im running it in my K15 Sierra
